Abstract

This paper aims to develop a shrinkage prediction model for self-compacting concrete based on experimental data. The model focuses on predicting the behavior of concrete up to a period of 90 days, which corresponds to a construction time during which countermeasures can be taken. The model was designed based on an independent methodology that combines fuzzy logic and genetic algorithm. This methodology was applied for an experimental data set, and the obtained model was compared to other published data and the prediction model considered by the Eurocode. The results were verified by statistical analysis that confirmed the reliability of the proposed model.
